The musculocutaneous nerve pierces the coracobrachialis muscle and supplies it with innervation.
The main function of the musculocutaneous nerve is to innervate the muscles in the anterior compartment of the arm, including the biceps brachii muscle. It also provides sensory innervation to the lateral aspect of the forearm.
The C6 nerve root gives rise to the musculocutaneous nerve, which innervates the muscles in the arm such as the biceps. The C7 nerve root gives rise to the median nerve, which innervates muscles in the forearm and hand as well as provides sensation to the palm and fingers.
There are three main nerves found in the arm and hand: the ulnar nerve, median nerve, and radial nerve. The ulnar nerve supplies sensation to the pinky and part of the ring finger, the median nerve supplies sensation to the thumb, index, middle, and half of the ring finger, and the radial nerve supplies sensation to the back of the hand and thumb.
The radial nerve supplies the muscles of the arm and forearm and and is also the sensory nerve for the upper limb. It therefore helps in the movement of the upper limb and is also partly responsible for sensory feeling in part of the arm and forearm and hand

You probably cannot straighten your forearm because your musculocutaneous nerve is injured.
The musculocutaneous nerve pierces the coracobrachialis muscle and supplies it with innervation.
The musculocutaneous nerve innervates the muscles in the anterior compartment of the arm, including the biceps brachii and brachialis. It also provides sensory innervation to the skin on the lateral surface of the forearm.
The nerve that passes through the coracobrachialis muscle is the musculocutaneous nerve.

The biceps deep tendon reflex is controlled by the C5 component of the musculocutaneous nerve.
